CVE-2025-69421

Issue summary: Processing a malformed PKCS#12 file can trigger a NULL pointerdereference in the PKCS12_item_decrypt_d2i_ex() function.Impact summary: A NULL pointer dereference can trigger a crash ...

Issue summary: Processing a malformed PKCS#12 file can trigger a NULL pointer

dereference in the PKCS12itemdecryptd2iex() function.

Impact summary: A NULL pointer dereference can trigger a crash which leads to

Denial of Service for an application processing PKCS#12 files.

The PKCS12itemdecryptd2iex() function does not check whether the oct

parameter is NULL before dereferencing it. When called from

PKCS12unpackp7encdata() with a malformed PKCS#12 file, this parameter can

be NULL, causing a crash. The vulnerability is limited to Denial of Service

and cannot be escalated to achieve code execution or memory disclosure.

Exploiting this issue requires an attacker to provide a malformed PKCS#12 file

to an application that processes it. For that reason the issue was assessed as

Low severity according to our Security Policy.

The FIPS modules in 3.6, 3.5, 3.4, 3.3 and 3.0 are not affected by this issue,

as the PKCS#12 implementation is outside the OpenSSL FIPS module boundary.

OpenSSL 3.6, 3.5, 3.4, 3.3, 3.0, 1.1.1 and 1.0.2 are vulnerable to this issue.
